[Prior art and its problems] Blinds in double glazing
It is known that a curtain or the like is housed to reduce or block the incidence of solar radiation into the room, but in recent years it is not limited to this. Further, it has a function of selectively transmitting and suppressing various lights, a function of suppressing transmission of heat rays, and the like. There are considerable attempts to do so.

For example, Japanese Utility Model Publication No. Sho 56-45096 discloses that both surfaces of a slat made of a glass plate or the like sealed in double glass are made to have high reflection surfaces, for example, that a heat ray reflection film is provided. It mentions that the incidence of solar radiation into the room in summer is appropriately blocked and that it is easy to enter in winter. However, as will be described later, heat radiation from indoors, that is, radiation of far-infrared rays to the outdoors cannot be facilitated or effectively blocked.

In Japanese Utility Model Application Laid-Open No. 60-168800,
In the double glazing with built-in blinds, it is disclosed that at least one of the glass plates is a selective reflection glass plate having an emissivity of solar radiation energy of 0.2 or less, and further, a heat ray reflective coating is appropriately formed on the outdoor side surface of the blind slat. Have been. Also in the present disclosure example, since the selective reflection glass is fixed as a window material and the angle cannot be adjusted, adjustment such as facilitating the emission of far-infrared rays from indoors to the outdoors or effectively blocking out cannot be performed.

Further, Japanese Patent Application Laid-Open No. 63-176584 discloses that a blind, a curtain or the like which transmits visible light is built in a multiple window made of a plate made of glass or the like.
Or, there is visible light transmittance on the indoor side of the indoor side plate,
It is disclosed that a layer having a small long-wavelength emissivity was formed. In this case, it is difficult to efficiently transmit and block both solar radiation mainly having near infrared rays and far infrared rays from indoors. Also, in any of the above known examples,
Unique for opening and closing blinds as in the present invention
It does not have any rotating and driving means.

[0006] Infrared rays are also called heat rays, and have a wavelength of about 0.
An electromagnetic wave with high thermal energy of .8μm or more. Solar radiation radiated from the sun and reaching the surface directly has a wavelength of 2.
Near-infrared rays of 1 μm or less or electromagnetic waves having a shorter wavelength occupy the majority.

However, what is usually referred to as a heat ray reflective glass or a heat ray reflective film has a higher reflectance of visible light or near-infrared light having a wavelength of about 2.1 μm or less than ordinary glass.
In the case of far-infrared rays having a longer wavelength, those exhibiting little reflection performance or having extremely low reflectivity as compared with low-emissivity films are effective, and are therefore effective in blocking and transmitting sunlight including near-infrared rays.

On the other hand, a so-called mid-infrared ray or far-infrared ray having a wavelength of more than 2.1 μm (hereinafter, referred to as far-infrared ray in the present invention) is radiated from a warm body such as a human body or a heated object.

[0009] Low emissivity glass or low emissivity film is
Visible light or the near-infrared ray is easy to transmit, but it blocks or reflects the far-infrared ray. According to the test method specified in JIS-R 3106, the vertical emissivity is 0.3 to 0.4.
It means the following.

In the present invention, a heat reflecting film for reflecting sunlight containing near-infrared rays to a blind slat, and a low-radiation film having a vertical reflectance of 0.2 or less for effectively reflecting far-infrared rays radiated from a warm body indoors. By appropriately adjusting the slat angle, the solar radiation is efficiently reflected to the outdoor side in summer, and the indoor infrared rays are radiated to the outdoor side to suppress the rise in indoor temperature. To open and close the blinds , especially the blinds, which reduce the indoor temperature by blocking the far-infrared rays emitted from the indoors, thereby reducing the cooling and heating load and significantly improving the energy-saving effect. Peculiar rotation, drive to do
It is intended to provide a double-glazed glass having a moving means .
